Network antenna TELTONIKA PR1URF51, 5 dBi, 2.4–2.4835 GHz, RP‑SMA male, 50 Ω, linear polarization, 195 mm, black

The Teltonika PR1URF51 is a compact external network antenna offering 5 dBi gain for the 2.4–2.4835 GHz frequency band. With a 50 Ω impedance and an RP‑SMA male connector, this linear‑polarized antenna is designed to enhance signal strength and reliability for Wi‑Fi and other 2.4 GHz wireless applications. Its 195 mm length and black finish make it suitable for installations where a discrete, space‑efficient external antenna is required.

Advantages

The PR1URF51 provides a moderate 5 dBi gain that balances improved range and maintained radiation pattern consistency. The RP‑SMA male connector ensures compatibility with many consumer and industrial routers, gateways, and access points that accept reverse polarity SMA interfaces. Linear polarization and 50 Ω impedance match common Wi‑Fi equipment, facilitating straightforward integration without additional matching components. Its compact 195 mm size and black color allow for unobtrusive mounting in indoor or sheltered outdoor locations.

Suitable for

• Enhancing Wi‑Fi coverage for routers, access points and repeaters operating in the 2.4 GHz band
• Improving signal reliability for IoT gateways and wireless sensors using 2.4 GHz links
• Use with network devices that accept RP‑SMA male antenna connectors

Key specifications

How to use

Install the PR1URF51 by screwing the RP‑SMA male connector into the corresponding RP‑SMA female adapter or device port until secure; avoid excessive force. Position the antenna vertically for typical omnidirectional coverage in the horizontal plane, or adjust orientation to match the polarization of paired devices for optimal performance. Place the antenna clear of large metal obstructions and, if used outdoors, in a sheltered location to reduce exposure to weather. Ensure the connected device is powered down or follow the device manufacturer's instructions when attaching or detaching the antenna.

Recommendations

For consistent 2.4 GHz performance, verify that the device's antenna connector type matches RP‑SMA male and maintain a clear line of sight where possible. Combine the PR1URF51 with compatible Teltonika or third‑party network equipment rated for 50 Ω systems, and check local regulations for allowed transmit power and antenna use.
